Application filed November 4, 1908. Serial No. 481,071.

Be it known that I, LEONARD R. S'lEEL, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of l iisconsin, have invented new and useful Improvements in Heat-Insulated Re.- ceptacles, ofwhich the following is a specification.

My invention relates to improvements in tubes or receptacles for-"bottles, and its primary object is the provision of a tube or receptacle in whichthe contents of the bottle may be kep l at a predetermined temperature without the use of a refrigerating or heating medium, thetube or receptacle bein especially designed for the reception of the bottle disclosed in my co-pcnding application filed -November 4, 1908, and serially numbered A further object of the invention is the provision of a tube or receptacle which may bereadily and quickly cleaned, which may be manufactured and sold at a comparatively low cosh-and which shall be simple of construction. I

With the above and other objects 111 View,

' the invention consists in the combination and arrangement of parts hereinafter fully described and claimed, and illustrated inthe accompanying drawing, wherein Figure l is a sectional view of a tube or receptacle constructed in accordance with my invention, the section being taken on a plane extending centrally and vertically through the tube'or receptacle, and Fig. 2 is a View in side elevat n thereof, the closure being removed.

Referring to the drawing by reference nu.-

merals, 1' designates a cylindrical casing" fully open at its upper and lower ends. The lower end of the casing is closed. by a bottom 2 which is provided with an upstanding a nnular flange 3, said flange receiving the lower end of the casing. Theupper portion of thecasing 1 is formed to PIOVldQ an upwardly and 1nwardly inclined flange 4. T he inner casing 5 which is also cylindrical is mounted within the outer casing 1. The inner-casing isilonger than the outer casing and has a diameter smaller than that of the outer casing'. The lower end of the inner casin 5 is offset inwardly as at '6 and is close by means of a bottom 7 which is proirided with an upstanding flange 8 receiving the lower end of the otfset portion 6. That are secured together by any suitable means. The lining is such to retard t.lie aass ige of heatand cold therethrough, The s er end of the lining is provided with a metallic member 12 while thelowcr end thereof is provided with a metallic member 13, the layer of tin foil being interposed between the liniru and said. member.

The tube or receptacle provided. with. a removable closure M1.- lihe closure coinprises an outer cylindrical wall and an inner cylindrical wall 16 which are relatively spaced. The closure also comprises an outer circular wall 17 and an inner circular wall 18 which are relatively spaced, the walls 17 and 1.8 being provided with flanges 1.5) and 20, which embrace the walls 15 and 16 respectivelv A lining which also consists of inner and outer layers l9 of closure. The tin foil oi? this lining is also provided with a coating of mercury and the layers thereof are secured together by any suitable means. The lower portion. of

- this lining is provided with a metallic menu her 21, and the upper portion thereof is provided with a metallic member 522, a layer of tin foil 23 being interposed between the member?! and the lining. The lower por-.

tion of the inner wall 16 and the closure 14; i

is inclined as at 24, said inclined'portion engaging the flange 14 of the receptacle 5 when the closure is in applied positl'bn. a point above the inclined portion 2st the 111- ner wall 16 of the closure let is threaded as the inner casing 5.

In practice the lower end otthe bottle is placed in the reduced portion 6 ol' the inner casing 5, leaving a space between the side Walls of the body and the casing. Theair in such space assists the lining in preventing the contents of the bottle from absorbing at 25 for engagement with the threads 9 of heat from the atmosphere and preventing the conduction of heat from the contents of the bottle.

The tube or receptacle may be readily cleaned and 'it may be manufactured and sold at a comparatively low cost.

Changes in the t'orm proportions and minor details of construction may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the iDVti-lltiOlL Having thus described the invention, what is claimed as new is 1,. A tube or receptablc comprising an outer casing provided with an upwardly and inwardly inclined flange an inner casing provided with a downwardly flaring flange engaging the flange of the outer casing, and

.a closure removably secured to the inner casing.

2. A tube or reeeptable comprising an outer casing with an upwardly and inwardly inclined flange, an inner casing provided with a downwardly flaring flange engaging the'flange of the outer casing, and a closure removably secured to the inner casing, said closure having an inclined portion engaging the flange of the inner casing.

A tube .or receptacle comprising innor and outer casings, a. lining between the casings, the inner casing and its lower p0r- Lion otl'set inwardly, the vertical wall of the said oli'sct portion being spaced from the lining, and a. closure.

it. A tube or receptacle comprising in nor and outer casings, a closure, and a linilng located between the bottom and side walls of the casings, said lining consisting of outer layers of paper and an intermediate layer of tin foil coated with mercury.

in testimony whereof I atlix my signature in presence of two witnesses.
